Does anybody know what the laws are for towing reqarding a cdl. The reason I ask is because I read an article that said if you race for money(drag racing) that you are considered commercial and that you would be required to have a cdl. I know that if you have a combined weight of 26000 pound(truck and trailer) or that you pull a trailer over 10000 pounds that you need a cdl and that you would be required to carry a log. Here is a link to the website.
